More than 20 people have been arrested in London after a protest in support of the banned group Palestine Action, the Metropolitan Police has said. Pictures from the demonstration showed a small group holding placards reading "I oppose genocide, I support Palestine Action" in Westminster.

More than 20 people have been arrested during a protest in London in support of Palestine Action, a group which has been banned under UK anti-terrorism laws.

The protest group was officially classified as a terrorist organisation from midnight on Saturday after the measure received overwhelming support from MPs and following the failure of a last-minute legal challenge to delay it.
